Denis de Jesus Lima Guerra, a co-author on 11 chemistry papers that were retracted in 2011 for suspicions of fraud, has lost his position at the Federal University of Mato Grosso (UFMT).
The paper was titled “Targeting pseudoknots in H5N1 hemagglutinin using designed aptamers,” and was written by Priyanka Dhar, Sayak Ganguli and Abhijit Datta, of the Defence Institute of High Altitude Research and the Bioinformatics Centre at Presidency College in Kolkata.
The Journal of Asian Earth Sciences has retracted a 2004 article by a scholar in India who resused text from a previous work on which he was a co-author.
The article, “Finite strain and deformation from a refolded region of the Dudatoli-Almora Crystalline, Kumaun Lesser Himalaya,” was written by Hari B. Srivastava, of Banaras Hindu University in Varanasi. Here’s what it had to say: Read the rest of this entry »
A team of physicists has lost their 2013 paper in the Journal of Optics after the publisher learned that the article had already appeared in print twice before.
The article, “Inscription of narrow bandwidth Bragg gratings in polymer optical fibers,” came from researchers at the Instituto de Telecomunicacoes, in Portugal, and the Aston Institute of Photonic Technologies, in Birmingham, England. Per the abstract: Read the rest of this entry »
On Saturday, we highlighted a great two-part series by Joseph Neff of the News & Observer diving into the story of “Stefan Franzen, a chemistry professor at North Carolina State University who has been trying unsuccessfully to correct the scientific record.” Today, that series became a three-part series, with a new story revealing that an investigation by the National Science Foundation (NSF) Office of the Inspector General (OIG) had found “reckless” falsification in the work in question.
One of the key papers in the controversy was published by Lina A. Gugliotti, Daniel L. Feldheim, and Bruce E. Eaton in Science in 2004 and cited 125 times, according to Thomson Scientific’s Web of Knowledge. (Eaton is now at the University of Colorado at Boulder.) In 2011, Nature reported on the situation: Read the rest of this entry »
The physics journal Pramana — a publication of the Indian Academy of Sciences — has retracted two studies by a group of researchers in Malaysia who appear to have cobbled together their papers from other sources.
The 2007 articles came from A.R.M. Yusoff, M.N. Syahrul and K. Henkel, of the University Science Malaysia, in Penang. One was titled “High resolution transmission electron microscope studies of a-Si:H solar cells,” and the other, “Hydrogenated nanocrystalline silicon germanium thin films.” The retraction notices are identical, and read: Read the rest of this entry »
More than two years ago, we wrote about a retraction for duplication in Biophysical Journal prompted by an email from pseudonymous whistleblower Clare Francis. That post generated a robust discussion, including one comment from someone calling himself or herself “Double Dutch.”
This past weekend, the last author of that paper, Rienk van Grondelle, left a lengthy response to that comment in which he explained how the duplication happened. We’ve confirmed that it was van Grondelle who left the comment, which we reproduce here in full (we’ve added paragraph breaks for readability): Read the rest of this entry »
